Twin flocker



INVENTOR HasAe/l A Sullivan July 11, 1961 H. A. SULLIVAN TWIN FLOCKER Filed 001;. 5, 1958 United States Patent 2,991,944 TWIN FLOCKER Haskell A. Sullivan, 442 165th St., Hammond, Ind.

Filed Oct. 3, 1958, Ser. No. 765,141 a '3 Claims. (Cl. 239-304) This invention relates to coating apparatus and more particularly to a flocking machine for simultaneously spraying a fiber and adhesive material.

It is an object of the present invention to provide a spray unit that may be conveniently operated by a conventional vacuum cleaner which will simultaneously spray a fiber mass and adhesive material so as to enable such combined spray to be directly applied for decorative, insulative, and accoustical purposes upon any desired surface.

Another object of the present invention is to provide a flocking machine of the above type having a self contained adjustable valve member for controlling the combined mixture of the adhesive and fiber mass.

Other objects of the invention are to provide a flocking machine bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:

FIGURE 1 is a side elevational view, with parts broken away, of a twin flocker made in accordance with the present invention; and

FIGURE 2 is a longitudinal cross sectional view taken along line 22 of FIGURE 1.

Referring now more in detail to the drawing, a twin flocker unit made in accordance with the present invention is shown to include an elongated hollow main body member 12 having a bell shaped fluid pressure inlet 14 at one end, within which another pressure fluid supply duct 16 is disposed. This fluid pressure inlet 16 supplies air pressure through a conduit 18 that has a discharge opening 20 at the front end of the main body member 12, which conduit 18 is adapted to facilitate the entrainment of liquid adhesive 28 disposed within a Vessel 26. A duct 24 with a discharge outlet 22 is disposed within the interior of the conduit 18. This container or vessel 26 is removably secured to a closure cap member 34 integrally carried by the main body member 12 and through which an outlet 32 of a fluid pressure supply line communicates. It will thus be recognized that as pressure is supplied to the interior of the vessel 26 through the line 34 and fluid passes outwardly through the conduit 18 under pressure, the adhesive liquid 28 will be directed outwardly through the outlet 20 in a fine stream.

Another closure cap 36 secured to the main body member 12 detachably supports a second vessel 38 adja cent to the bell shaped end 14 of the main body member 12. This vessel 38 contains a mass of fiber material 40 which is adapted to be directed outwardly through an outlet 48 in the closure cap 36 and main body member 12 in response to a supply of pressure fluid entering the vessel 38 through a duct 46 which is in communication with the interior of a bell-shaped pressure chamber 14 through a port 42. The size of the opening of this port 42 is conveniently controlled by an adjustable valve member 44 so as to control the ratio of the fibrous material being ejected compared to the quantity of the adhesive material being dispensed. When air is supplied under pressure to the interior of the vessel 38 through the line 46, and when air is delivered outwardly through a port 54 in a partition wall 56 within the main body member 12 which ultimately passes outwardly through 2,991,944 Pat ted July 11, 1 .61

the nozzle 52, the fiber mass is dispensed outwardly through the discharge opening 58 in the front of the main body member 12 after being delivered to the in= terior thereof through the outlet 48.

The operation of this device will now be readily understood. Adhesive liquid is placed within the front vessel 26 and the fiber mass is placed within the rear vessel 38. By connecting a conduit 60 to the bell shaped end 14 of the main body member 12 fluid pressure is simultaneously supplied to each of the ducts 16, 30; 46, 50, so as to properly pressurize the front and rear vessels 26, 38, respectively, to entrain the adhesive liquid and fibrous mass within the jet stream passing outwardly though the respective outlets 20, 58. The ratio of the fiber to the adhesive mass is controlled by adjusting the valve member 44 to control the size of the opening 42.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:
